In this activity, students explore past examples of climate variability in three locations: the Peruvian and Bolivian Andes, Central America, and coastal Greenland, and consider differences between climate variability and climate change.

This 3-activity sequence addresses the question: &amp;quot;To what extent should coastal communities build or rebuild?&amp;quot; The activity uses social science and geoscience data to prepare an evidence-based response to the question, in targeted US coastal communities.
